Exam 8: Causal Research Design: Experimentation

An experimental design in which the experimental group is exposed to the treatment but the control group is not and no pretest measure is taken is called the posttest-only control group design.

An effect in which a prior measurement affects the test unit's response to the independent variable is called nonresponse bias.

Consumers are good examples of dependent variables.

________ variables are variables that are manipulated by the researcher and whose effects are measured and compared.

Opinions,tastes,and preferences in virtual worlds are the same as in a real setting.

A time series design that includes another group of test units to serve as a control group is called a multiple time series design.

"History" refers to the occurrence of events before the experiment.

In a short essay,describe the four broad categories of experimental designs and discuss the various applications of each design category.

In the virtual world,it is more complex but much less costly to manipulate the independent variable and control for mediating variables than it is in the real world.

Which of the following is NOT an extraneous variable?

According to the text,experiments can be described in terms of all of the following EXCEPT:

A time series design that includes another group of test units to serve as a control group is called a(n)________.

An experimental design in which the test units are assigned randomly and the experimental group is exposed to the treatment but the control group is not and no pretest measure is taken is called the ________.

According to the text,experiments can be described in terms of interdependent variables.

Variables,other than the independent variables that influence the response of the test units are called ________.

With experimental designs,it is possible to control for some of the extraneous variables.

According to the text,which of the following are the most common statistical designs?

According to the text,an experimental group is the group exposed to the manipulated independent variable.

A ________ involves measurement of behavior,attitudes,or perceptions in the environment in which they occur.

Responses given because the respondents attempt to guess the purpose of the experiment and respond accordingly are called ________.
